Rabbit Anti-STX3 Recombinant Antibody (CBXS-1609) (CBMAB-S4458-CQ)

Syntaxin 3

The gene is a member of the syntaxin family. The encoded protein is targeted to the apical membrane of epithelial cells where it forms clusters and is important in establishing and maintaining polarity necessary for protein trafficking involving vesicle fusion and exocytosis. Alternative splicing results in multiple transcript variants.

STX3A

Potentially involved in docking of synaptic vesicles at presynaptic active zones. Apical receptor involved in membrane fusion of apical vesicles.
Isoform B
Essential for survival of retinal photoreceetors.
Isoform 3
Functions as a regulator of gene expression.

Retinal dystrophy and microvillus inclusion disease (RDMVID):
An autosomal recessive disease characterized by early-onset, severe retinal dystrophy associated with intractable congenital diarrhea. Intestinal biopsies show loss of microvilli, microvillus inclusions, and accumulation of subapical vesicles in villus enterocytes.
Diarrhea 12, with microvillus atrophy (DIAR12):
An autosomal recessive congenital enteropathy characterized by intractable secretory diarrhea, resulting in severe dehydration and metabolic acidosis. DIAR12 can be diagnosed based on variable loss of brush-border microvilli, microvillus inclusions, and accumulation of subapical vesicles in villus enterocytes.
